Application filed March 22, 1905. Serial No. 251.867.

To all whom t may concern:

Be it known that I, SARA SCOTTER, a subject'of the King of GreatBritain, residing at 14 Brunswick Place, Hove, Brighton, in the countyof Sussex, England, have invented certain new and useful Improvements inFire- Escapes, of which .the followingis a specification.

The improvements relate to a fire-escape` leaves which fold back and is'made to suit the width of any window or other opening. The half of thehinged cover adjoining the window when folded back rests upon the bottomof the window-frame, thus forming a saddle. On the under side of thissaddle are two rollers, upon which the escape-ladder runs. The ladderitself is flexible. of this ladder is a collapsible cradle of nreproofedcanvas, to which are attached guideropes, which, as an additionalprecaution, may be held by any one in the street to help to guide theladder in its iirst descent. The ladder winds vupon a roller or drumfitted inside the chest, which is worked by'means of toothed gearingattached to a crank or handle at one side of the chest. When the wholeof the ladder is wound over the drum, the cradle folds over and restsupon the ladder at the top of the chest, just inside the cover. There isalso a second roller or drum inside the chest, smaller than the first,but similarly worked by gearing, and an outside handle, round which arewound two steel or other ropes, attached to a 'second collapsible On oneside of this second cradle are fixed two rollers, which allow it to bequickly run down the face of the ladder and quickly raised at will i forfresh service.

The chest contains all the necessary iittings, (drums, gearing, ladder,cradles, ropes, &c.,) so that when the cover is shut it forms a verycompact piece of furniture.

'Referring toV the accompanying drawings, Figure 1 is a plan showing thechest in front I At the bottom' of a window. Fig. 2 is a side view. Fig.3 is a front View. Fig. l is a side view of cradle No. 2, showing therollers which run along the face of the ladder and also showing theguide-ropes. Fig. 5 is a View of the chest with its wall bro en away.Fig. 6 is a perspective view showing the application of the device to awindow-frame.

A is the chest, containing one large dru'rn B, upon which is wound theescape-ladder, and also a smaller drum C, upon which are wound the twosteel ropes attached to cradle No. 2. The drums are worked by toothedgearing attached to handles on the outside of the chest.

D is the ladder, of steel wire.

E is cradle No. 1, which is collapsible and attached to the end of theladder. Attached to E are guide-ropes.

F F are small rollers on the under side of one half of the hinged covertothe chest, over which the escape-ladder runs.

G is the part of the hinged cover to which the rollers F F are fixed.This part when opened back rests upon the bottom of the Window-frame. Itis previously referred to as the saddle H is the other or second part orhalf of the opening cover, hung upon` strong hinges and adapted to foldback over the front of the chest.

I is the handle or crank for working the large drum B, attached totoothed gearing.

J is the handle for working the smaller drum C, attached to gearingsimilarly to I.

K K are casters upon which the chest may be run.

L L are the outside hinges to the part H of the divided cover. A similarpair would be fixed to the part G.

M is cradle No. 2, which is also collapsible and attached to two steelropes N, working over the drum C. This cradle slides down the face ofthe ladder D by means ofv two small rollers o o on one side.

P P are two small props on the under side of cradle No. 2.

R is the bottom part of the window-frame, upon which the part G of thecover rests when folded back.

S is the window-sill.

T is the outer wall of a building.`

U is the floor.

-V is the ceiling.

W is the window.

IOO

X is one of the guide-ropes to cradle No. 1.

Y Y are the toothed or cog Wheels or gearing attached to the drums andthe outside cranks or handles.

What l cla-iin, and desire to secure by Letters Patent of the UnitedStates, isd

1. A hre-escape comprising a receptacle with a hinged top in sections,one of which is constructed to form a saddle to engage over aWindow-sill, a drum in said receptacle, a second dru'ni in saidreceptacle, a flexible ladder Wound on the first-named dru'rn, a ropeWound on the other drum, and a cradle carried by said rope and adaptedto slide on said ladder.

2. A rire-escape comprising a receptacle With a hinged top in sections,one of Which is constructed to form a saddle to engage over aWindow-sill, a drum in said receptacle, a seeond drum in saidreceptacle, a leXible ladder Wound on the iirst named drum, a rope Woundon the other drum, and a cradle carried by said rope adapted to slide onsaid ladder and rollers on said saddle.

3. A fire-escape comprising a receptacle With a hinged top in sections,one 'of Which is constructed to forni a saddle to engage over aWindow-sill, a drum in said receptacle, a sec ond drum in saidreceptacle, a flexible ladder Wound on the iirst-narned drum,A a ropeWound on the other drum, and a cradle carried by said rope adapted toslide on said ladder, rollers on said saddle and a collapsible cradlecarried by said ladder.
